Comp Cams “OE R Series” Hydraulic Roller Lifters are designed as an OEM replacement, but with an increase in internal preload to prevent the lifter from bleeding off. This is the proper way to keep the lifter “pumped up” at high RPM's to prevent valve float.

These lifters are a perfect compliment to an aftermarket cam/stronger valvesprings combination and/or an increase in your shift points past the stock 5800rpm's.
